Abstract:
Andalusia is a region in the south of Spain where almost the 80% of the municipal solid waste (MSW) generated goes to landfill disposal. There are no waste-to-energy facilities in Andalusia, then the only option to eliminate the non-recyclable and non-compostable fraction of the MSW is landfilling. We propose the use of the MSW refuse converted into refuse derived fuel (RDF) as feedstock in a thermochemical biorefinery producing ethanol and electricity. The objective of this study is the assessment of the time-integrated GHG emissions of the facility for a 100-year time horizon. For that, a methodology based on pulse emission and radiative forcing has been developed. This kind of methodology is particularly important when the emissions are slowly produced for a period of time. Results show the impact of the landfill emissions are still considerable in the year 100 and higher than those of the fossil and bioenergy systems. MSW as feedstock can save GHG emissions and minimize the landfill disposal in regions as Andalusia.
